Network Segregation - Adding security
to Wireless Network
(or to any peer to peer Network).
Note* While this page is
demonstrating a specific way of protecting Wireless connection and the network
behind it, the principle can be used for other configurations.
Network segregation separates one Network into two LANs keeping the unsafe computers in the front Network and moving the computers that you would like to protect to a second shielded Network.
A simple segregation can be achieved by using two Entry Level Cable/DSL Routers.
If you are Not familiar with the protection that is provided by a Router read this.
Assuming that you have a Wireless Cable/DSL Router that is connected to your Broadband Modem and provides Internet sharing to few
Wired, and few Wireless computers
Unfortunately you would not be able to share files with using Windows File Sharing across the two Networks (regular file and printer sharing would work normally within each Network). The relation between your segregated Network and the front Network would be like the relation between the front Network and the Internet.
My favorite way to copy and move files between the two LANs is by using Remote control program (which can be found for free and it is easy to set) like this:
However you can configure other applications to achieve
the same goal (Windows Remote Desktop, Net Drive etc.)
Note: This type of configuration does not eliminate the need of Software Firewall, AntiVirus, and AntiSpyware programs. to be installed on both Networks computers.
As an example, you can maintain a less secure Wireless available for friends of the first Router, and use fully secured Wireless (WPA-AES) behind the second Router.
Or, you can connect the WAN port of the second Router through a Wireless Game Box card to the first Router, and thus replacing the connection between the two Routers with Wireless (get a Game Box that can secured with WPA).
